Environment and Enclosure
ATTENTION: This equipment is intended for use in a Pollution Degree 2 industrial
environment, in overvoltage Category II applications (as defined in IEC 60664-1), at altitudes up
to 2000 m (6562 ft) without derating. This equipment is considered Group 1, Class A industrial
equipment according to IEC/CISPR 11. Without appropriate precautions, there may be
difficulties with electromagnetic compatibility in residential and other environments due to
conducted and radiated disturbances.
This equipment is supplied as open-type equipment. It must be mounted within an enclosure
that is suitably designed for those specific environmental conditions that will be present and
appropriately designed to prevent personal injury resulting from accessibility to live parts. The
enclosure must have suitable flame-retardant properties to prevent or minimize the spread of
flame, complying with a flame spread rating of 5VA or be approved for the application if
nonmetallic. The interior of the enclosure must be accessible only by the use of a tool.
Subsequent sections of this publication may contain additional information regarding specific
enclosure type ratings that are required to comply with certain product safety certifications.
In addition to this publication, see the following:
• Industrial Automation Wiring and Grounding Guidelines, publication 1770-4.1
additional installation requirements.
• NEMA Standard 250 and IEC 60529, as applicable, for explanations of the degrees of
protection provided by enclosures.
, for
Preventing Electrostatic Discharge
ATTENTION: This equipment is sensitive to electrostatic discharge, which can cause internal
damage and affect normal operation. Follow these guidelines when you handle this equipment:
• Touch a grounded object to discharge potential static.
• Wear an approved grounding wriststrap.
• Do not touch connectors or pins on component boards.
• Do not touch circuit components inside the equipment.
• Use a static-safe workstation, if available.

Overview
The Micro800™ expansion I/O is a modular I/O that complements and extends the capabilities
of Micro850™ controllers. These expansion I/O modules interface with Micro850 controllers
using an I/O expansion port.

Mounting Dimensions and DIN Rail Mounting
Publication 2085-IN005B-EN-P - September 2012
Micro800 8-Point Input and 8-Point Output AC Modules 7
TIP
DIN Rail Mounting
The module can be mounted using the following DIN rails: 35 x 7.5 mm x 1 mm
(EN 50 022 - 35 x 7.5)
For environments with greater vibration and shock concerns, use the panel mounting
method, instead of DIN rail mounting.
Before mounting the module on a DIN rail, use a flat-blade screwdriver in the DIN rail latch and
pry it downwards until it is in the unlatched position.
1. Hook the top of the DIN rail mounting area of the module onto the DIN rail, and then
press the bottom until the module snaps onto the DIN rail.
2. Push the DIN rail latch back into the latched position.
Use DIN rail end anchors (Allen-Bradley part number 1492-EAJ35 or 1492-EAHJ35)
for vibration or shock environments.
.
ATTENTION: This product is grounded through the DIN rail to chassis ground. Use zinc plated
yellow-chromate steel DIN rail to assure proper grounding. The use of other DIN rail materials
(for example, aluminum or plastic) that can corrode, oxidize, or are poor conductors, can result
in improper or intermittent grounding. Secure DIN rail to mounting surface approximately every
200 mm (7.8 in.) and use end-anchors appropriately.
To remove your module from the DIN rail, pry the DIN rail latch downwards until it is in the
unlatched position.
Panel Mounting
The preferred mounting method is to use two M4 (#8) per module. Hole spacing tolerance:
±0.4 mm (0.016 in.). For mounting dimensions, refer to Micro830 and Micro850
Programmable Controller User Manual, publication 2080-UM002
Follow these steps to install your module using mounting screws.
1. Place the module next to the controller against the panel where you are mounting it.
Make sure the controller and module are spaced properly.
2. Mark drilling holes through the mounting screw holes and mounting feet then remove
the module.
3. Drill the holes at the markings, then replace the module and mount it.
Leave the protective debris strip in place until you are finished wiring the module and
any other devices.

8 Micro800 8-Point Input and 8-Point Output AC Modules
System Assembly
The Micro800 expansion I/O module is attached to the controller or another I/O module by
means of interconnecting latches and hooks, as well as the bus connector. The Micro850
controller and expansion I/O modules must terminate with a 2085-ECR Bus
Terminator module.
Be sure to lock the module interconnect latches and tighten the RTB hold down screws before
applying power to the module.
For installation of the 2085-ECR module, refer to Micro800 Bus Terminator Module
Installation Instructions, publication 2085-IN002
ATTENTION: Failure to connect a bus terminator module to the last expansion I/O module will
result in a controller hard fault.
.
Field Wiring Connections
In solid-state control systems, grounding and wire routing helps limit the effects of noise due to
electromagnetic interference (EMI).
ATTENTION: Do not wire more than 2 conductors on any single terminal.
Wire the Modules
Included with your module is a single 12-pin Removable Terminal Block (RTB). Basic wiring of
the module is shown below.
